Description

Technical Field

[0001] The utility model relates to the technical field of rice polishing equipment, in particular to a single-roller rice polishing machine. Background Art

[0002] According to Chinese patent CN217747188U, a single-roller rice polisher is disclosed, which includes a drum, a polishing mechanism and a driving mechanism; the drum is a cylindrical metal drum, the upper end of the inner arc surface of which is rotatably connected to a rotating circular plate, a discharge port opened in the middle of the bottom end surface of the drum is provided with a discharge pipe, a valve is connected in series to the lower end of the discharge pipe, and a feed pipe is provided in the feed port opened at the upper end of the outer arc surface of the drum; the polishing mechanism is arranged in a mounting hole opened on the outer side of the upper surface of the rotating circular plate; the driving mechanism is arranged at the upper end of the outer arc surface of the drum through a T-shaped frame, and the left side of the driving mechanism is fixedly connected to the lower surface of the rotating circular plate. The single-roller rice polisher uses a single roller to polish rice, reduces rice fragmentation, and improves the polishing quality of rice. At the same time, it can drive the polishing roller to stir the rice while polishing the rice, thereby improving the polishing efficiency of the rice.

[0003] The utility model uses a single roller to polish rice, reduces rice breakage, and improves the polishing quality of rice. At the same time, the polishing roller can be driven to stir the rice while polishing the rice, thereby improving the polishing efficiency of the rice.

[0004] However, the above technical solution still has the problem that the operation of the polishing machine mainly depends on the friction between the polishing roller and the rice, while the polishing roller of the utility model cannot polish the edge of the rice when it is running, and the polishing range is small. Two motors are arranged inside the machine, which increases the cost of the machine. When there is too much rice raw material inside the machine, the polishing roller may not rotate but the motor itself may rotate, causing the machine to fail to operate normally. Motor No. 1 is connected through gears, and there are gaps between the gears, so it will shake when it is running. This structural shaking will cause parts to loosen, which may cause Motor No. 1 to fall off during operation and damage the machine itself.

[0005] Therefore, the utility model provides a single-roller rice polishing machine. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a single-roller rice polishing machine, which solves the problem that two motors are arranged inside the machine, which increases the cost of the machine. When there is too much rice raw material inside the machine, the polishing roller may not rotate while the motor itself rotates, causing the machine to fail to operate normally. Motor No. 1 is connected through gears, and there are gaps between the gears, so it will jitter during operation. This structural jitter will cause parts to loosen, which may cause Motor No. 1 to fall during operation and damage the machine itself.

[0007] To achieve the above purpose, the utility model is implemented by the following technical scheme: a single-roller rice polisher, including a polishing chamber, characterized in that a polishing mechanism is arranged inside the polishing chamber, and the polishing mechanism includes:

[0008] A polishing roller installed in the polishing chamber, one end of which is provided with a polishing unit for polishing the rice, the polishing unit comprising:

[0009] The transmission assembly comprises two fixed shafts fixedly connected to the inner cavity of the polishing chamber, the other ends of the fixed shafts are rotatably connected to the secondary gears, the surface of the inner cavity of the polishing chamber is rotatably connected to the rotating shaft, the surface of the rotating shaft is fixedly connected to the main gear, and the main gear meshes with the surface of the secondary gear;

[0010] A rotating assembly is arranged at one end of the polishing roller and is used to drive the polishing roller to run;

[0011] The supply unit is arranged on the surface of the polishing chamber and is used for conveying rice to the interior of the polishing chamber.

[0012] Preferably, the rotating assembly includes a fixed plate fixedly connected to one end of the polishing roller, the fixed plate is fixedly connected to the rotating shaft, a gear ring is sleeved on the surface of the fixed plate, and the gear ring is meshed with the surface of the sub-gear.

[0013] Preferably, the interior of the polishing roller is hollow, a plurality of holes are equidistantly provided on the surface of the polishing roller, a plurality of hemispherical blocks are equidistantly and fixedly connected to the surface of the polishing roller, a dense mesh cylinder is sleeved on the surface of the polishing roller, the dense mesh cylinder is fixedly connected to the gear ring, and the dense mesh cylinder is rotatably connected to the fixed plate.

[0014] Preferably, the other end of the polishing roller is fixedly connected with a clamping ring, and one end of the dense mesh cylinder is rotatably connected to the clamping ring.

[0015] Preferably, the replenishing unit comprises a feed pipe rotatably connected to the clamping ring, a clamping groove is provided on the surface of the feed pipe, and the clamping groove is fixedly connected to the water tank via a connecting pipe.

[0016] Preferably, a plurality of grooves are provided on the surface of the dense mesh cylinder, and a collecting box is rotatably connected to the surface of the dense mesh cylinder, and the grooves are located inside the collecting box.

[0017] Beneficial Effects

[0018] The utility model provides a single-roller rice polishing machine. Compared with the prior art, it has the following beneficial effects:

[0019] 1. The single-roller rice polisher is fixedly connected to the rotating shaft on a fixed plate, one end of the dense mesh cylinder is fixedly connected with a gear ring, and the gear ring is meshed with the surface of the sub-gear, and the fixed plate is rotatably connected to the dense mesh cylinder, which solves the problem that when the single-roller polisher is polishing, the rice falls on the external screen and can no longer contact the polishing roller, thereby ending the polishing operation. This makes it possible for the rice grains that have not completed the polishing operation to be discharged, resulting in an unsatisfactory polishing effect. If the proportion of unfinished polished rice is too large, it will be re-polished, and the proportion of broken rice will increase during the re-polishing process, thereby increasing the problem of loss.

[0020] 2. The single-roller rice polisher has a plurality of holes and grooves equidistantly formed on the surface of the polishing roller, a plurality of hemispherical blocks equidistantly fixedly connected to the surface of the polishing roller, and a dense mesh cylinder sleeved on the surface of the polishing roller. This solves the problem that the polisher rotates at high speed during operation to frictionally polish the rice. The single roller is often slow during the polishing operation, and the polisher needs to be started after a certain amount of rice is put into the polisher. After the polisher is started, the material needs to be re-fed into the polisher, which is cumbersome to operate, complicated in process, and requires manual auxiliary observation, which is time-consuming and laborious.

The fixed plate 321 is rotatably connected to the dense mesh cylinder 6, which solves the problem that when the single-roll polisher is polishing, the rice falls on the external screen and can no longer contact the polishing roller, thereby terminating the polishing operation. This means that the rice grains that have not completed the polishing operation can only be discharged, resulting in an unsatisfactory polishing effect. If the proportion of rice that has not completed polishing is too large, it will be re-polished, and the proportion of broken rice will increase during the process, thereby increasing the problem of loss.

[0033] In this embodiment, the rotating assembly 32 includes a fixed plate 321 fixedly connected to one end of the polishing roller 2. The fixed plate 321 is fixedly connected to the rotating shaft 313. A gear ring 322 is sleeved on the surface of the fixed plate 321, and the gear ring 322 meshes with the surface of the sub-gear 312.

[0036] In this embodiment, the replenishing unit 7 includes a feed pipe 71 rotatably connected to the clamping ring 8. A clamping groove 72 is provided on the surface of the feed pipe 71. The clamping groove 72 is fixedly connected to a water tank 73 via a connecting pipe.

[0037] In the present embodiment, a plurality of grooves 10 are provided on the surface of the dense mesh cylinder 6, a collecting box 9 is rotatably connected to the surface of the dense mesh cylinder 6 and the grooves 10 are located inside the collecting box 9, a plurality of holes 4 are equidistantly provided on the surface of the polishing roller 2, a plurality of hemispherical blocks 5 are equidistantly fixedly connected to the surface of the polishing roller 3, and a dense mesh cylinder 6 is sleeved on the surface of the polishing roller 3, thereby solving the problem that the polishing machine relies on the polishing roller to rotate at high speed during operation, thereby frictionally polishing the rice, a single roller is often slow during polishing operation, and the polishing machine is started after a certain amount of rice is put into the polishing machine, and after completion, the polishing machine needs to be re-fed, the operation is cumbersome, the process is complicated, manual auxiliary observation is required, and it is time-consuming and labor-intensive. At the same time, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0038] During operation, the driving motor is started by an external power supply, and one end of its output shaft drives the rotating shaft 313 to rotate through a coupling, and the rotating shaft 313 drives the polishing roller 2 to rotate through the fixing plate 321, and the rotating shaft 313 drives the main gear 314 to rotate, and the main gear 314 drives the gear ring 322 to rotate in the opposite direction through the sub-gear 312, and the gear ring 322 drives the dense mesh cylinder 6 to rotate, so that the polishing roller 2 and the dense mesh cylinder 6 rotate in opposite directions, and at the same time, the polishing roller 2 at the other end drives the clamping ring 8 to rotate, and the clamping ring 8 and the dense mesh cylinder 6 rotate in the opposite direction. At this time, rice is put in through the feeding pipe 71, and the water tank 73 sprays a proper amount of water on the surface of the rice through the clamping groove 72. The rice then enters the polishing roller 2 for polishing, and then falls to the outside through the holes due to centrifugal force. When it falls to the inner cavity of the dense mesh cylinder 6, the dense mesh cylinder 6 rotates to bounce the rice, and then the hemispherical block 5 contacts and rubs the rice to achieve the effect of multiple polishing cycles, while broken rice and dust will fall to the bottom of the inner cavity of the polishing chamber 1 through the mesh holes of the dense mesh cylinder 6, and then the polished rice falls into the collection box 9 through the groove 10 on the other side, completing the polishing operation.
